Over Revving

Featured Replies

Hi , I have a Beta Rev 3 250cc (2005 ).Recently I took the carb off to clean it (not an easy job ! ).

When I have put it back together and started the bike it over revs,tried to turn the tick -over down with the two adjustment screws but it still over revs. Anybody know why my bike is doing this ?.Hopefully there is a simple solution but I don`t seem to be able to work it out myself. Your help would be much appreciated.

Have you routed the throttle cable correctly? Did you tighten the elbow on top of the carb? Is the cable seated in the elbow properly?

With the engine off, when you open the throttle and let it go can you hear it hitting the stop ?

If not investigate as above.

after refit, always check the slide is fully closed, hold your finger on the carb and twist throttle fully open and let go ! you should feel a metallic clunk on you finger, telling you the slide is closing. no racing engine speed! on startup

Also...........there is a hassle free way of removing carb.It doesn't have to be a pig.It is well described in the Beta forum.
